What is fog?

That is the question that was asked this morning on our way to school. As we are walking my two little munchkins were having another deep conversation about the fog. Here's what fog is according to Chrsitian.

Ashlee: "boy there sure is a lot of fog this morning"

Christian: "yeah, and you know what fog is Ashlee?"

Ashlee: "what?"

Christian: "it's clouds that died".

Well, there you have it!
